Yes, you are. LVP approval is dependent on the aeroplane certification, AOC, local CAA and many others. It is entirely possible and not out of ordinary that two companies, using same aeroplanes, under same CAA have different requirements and procedures for CAT 2 & 3 approaches - it's the matter of what was written on application for LVP approval and what was demonstrated. As for me, ATR could do either automatic or manual cat 2. Airbus was strictly automatic approach but manual landing could be done from CAT2 and not from CAT3. Q400 can either do automatic CAT2 without Head-up Guidance System or manual CAT2 or 3A, using HGS. No autoland there.

Could be that minima have moved downwards since I got certified on Q400 or i might by type/installation specifi, but the way we do it is CAT3A - 50 ft min DH and 200m RVR and doing HGS approach into actual 200m RVR is one of the most exciting things I've done in an aeroplane - it beats spinning Zlin 142 by wide margin. I don't like too much excitement when flying for subsistence.
